Abstract: Disclosed is a drive circuit for a digital dimming LED light, relating to the LED light drive circuits, which includes a power module and a dimming module corresponding to the LED lights, wherein the dimming module comprises a demodulation unit, a boosting constant voltage unit and a constant current chopper unit, and the power module is used to convert a utility power into DC power and output it to the demodulation unit, and to receive an external dimming signal and modulate and convert it into a digital signal. The demodulation unit is connected to the power module for receiving and demodulating the digital signal, the constant current chopper unit is connected to the demodulation unit, and both the boosting constant voltage unit and the constant current chopper unit are connected with the LED lights, so that the brightness of the LED lights is consistent.
